内部重定向-PHP和.htaccess？

Question

Good evening, I wanted to know if it is possible to redirect a request to my page as http://test.diogo.me to the page with the content -> http://www.diogo.me/pages/test/ (this redirection must be internal... the browser should point to http://test.diogo.me ). I have been reading about .htaccess and I feel that this is the resolution for me.
I have tried with the following code:

 <IfModule mod_rewrite.c>
RewriteCond %{HTTP_HOST} !^www\.diogo\.me [NC]
RewriteCond %{HTTP_HOST} ([^.]+)\.diogo\.me [NC]
RewriteRule ^(.*)$ /%1/$1 [L]

The output is error 404 file not found :(
Am I going in the right track?
Sorry about my expressing limitations. Thanks in advance

Answer 1

Just put this code in your .htaccess and remove your existing lines from there:

Options +FollowSymLinks -MultiViews
RewriteEngine on

RewriteCond %{HTTP_HOST} ^test\.diogo\.me$ [NC]
RewriteRule ^$ http://www.diogo.me/pages/test/ [L,P]

Answer 2

You were missing the /pages part

RewriteCond %{HTTP_HOST} !^www\.diogo\.me [NC]
RewriteCond %{HTTP_HOST} ([^.]+)\.diogo\.me [NC]
RewriteRule ^(.*)$ /pages/%1/$1 [L]

Assuming the subdomains have the same document-root as the main domain.
